The ethanolic extract obtained from roots of Operculina turpethum (Convolvulaceae) were evaluated for hepatoprotective activity in rats by inducing liver damage by paracetamol. The ethanol extract at an oral dose of 200 mg/kg exhibited a significant protective effect by lowering serum levels of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase and total bilirubin. These biochemical observations were supplemented by histopathological examination of liver sections. Silymarin was used as positive control.
